response function to process variables is unknown. Although RSM
can be an efficient method, it is not used much in oil optimization
problems (Meddaugh et al., 2005). A few studies have reported the
use of design of experiments method in oil industries (Rashid et al.,
2012); however due to the large scale of the oil industry, modeling
and simulation(M&S) is important because it helps in saving
money in systems testing. M&S is cheaper than building the system
or doing the experimental work at a real scale and performing test
cases on that condition. Also time constraints that professionals in
the industry often deal with can be another reason for choosing
M&S. Therefore instead of a thorough data acquisition in primary
levels of the projects, managers tend to use the results of simulations
and modeling for their projects
